Type of animation
Android animation is made up of four different types
in XML
Alpha |
Gradient Transparency Animation effect |
Scale |
Gradient Dimension Stretch animation effect |
Translate |
Move animation effect on picture transition position |
Rotate |
Picture Transfer rotation animation effect |
In Javacode
Alphaanimation |
Gradient Transparency Animation effect |
Scaleanimation |
Gradient Dimension Stretch animation effect |
Translateanimation |
Move animation effect on picture transition position |
Rotateanimation |
Picture Transfer rotation animation effect |
Android Animation mode
Animation There are two main modes of animation:
One is tweened animation (gradient animation)
in XML |
Javacode |
Alpha |
Alphaanimation |
Scale |
Scaleanimation |
One is frame by frame (Picture conversion animation)
in XML |
Javacode |
Translate |
Translateanimation |
Rotate |

- <!--
- Fromdegrees the angle at which the animation starts
- Todegrees the rotation angle of the object at the end of the animation, which means clockwise
- The Pivotx property is the start position of the animation relative to the X coordinate of the object
- The Pivoty property is the start position of the animation relative to the object's y-coordinate->

- Toxdelta, Toydelta, x, y coordinates at the end of the animation <!--
- Interpolator Specifying an animation insert
- Common with acceleration reducer accelerate_decelerate_interpolator
- Accelerate the accelerate_interpolator of the insertion device,
- decelerate the insertion device decelerate_interpolator.
- Fromxscale,fromyscale, the scale of X, y before the start of the animation, 0.0 for not showing, 1.0 for normal size
- Toxscale,toyscale, the multiple of the final zoom of the animation, 1.0 for normal size, greater than 1.0 magnification
- Pivotx, Pivoty animation start position, relative to the screen percentage, two are 50% means the animation starts from the middle of the screen
- Startoffset, the interval of time that the animation is executed more than once, which pauses the time before execution,
- Unit millisecond duration, the time that the animation effect consumes, the unit milliseconds,
- The smaller the value the faster the animation repeatcount, the animation repeats the count, the animation will execute the value + 1 times
- Repeatmode, the animation repeats the pattern, the reverse is reversed, and when the first even executes, the animation is in the opposite direction.
- Restart for re-execution, no change in direction--
